Character mistake: When Tony is talking to the Biancis and others, he refers to victim Kevin Turner as "Kevin Grant" at least two times. (00:44:50 - 00:46:27)
Character mistake: David said, "Camels bite. I hear they like to bite people in the stomach. It's the leading cause of death among the Arabs." This is absurd. Generally, leading causes of death are heart disease, cancer, diabetes, high blood pressure; auto accidents may be the leading cause for certain age groups, and deaths from infectious diseases may be increasing. Resorting to statistics on the deadliest "animals", camels are not even in the top 15. Deer and bees (#14-15) cause about 100 deaths each yearly. (00:24:15)
Character mistake: During the opening fight Jackie lands a punch on her opponent just after the round ends. The referee should've warned her about this as it's illegal in MMA to do this, and he didn't.
Character mistake: Valerie approached a group of wedding attendees fighting outside the venue, saying, "Break it up" a few times. When that didn't work, she fired two "warning shots" into the air. The second shot was aimed more toward the brick porch/overhang. In general, warning shots are not permitted and it is illegal to discharge a weapon in a public place, except in the line of duty when faced with imminent threat of serious bodily injury or death. There was no justification to discharge her firearm. (00:05:20)
Character mistake: Amber was a poster artist and Ben was a musician. Amber said to Serena, "You know a lot of people and can afford rent, so why do you want to live downtown?" The downtown area or center of a city is especially attractive to artists (as Amber should know) for its art/cultural/entertainment opportunities and experiences. Amber was also implying that it was more expensive to live in the suburbs than in a downtown apartment (where rent can be unaffordable to all but at least the upper-middle class). (00:07:20)
Character mistake: Detective King (?) told Mikey, "You're on probation. You got no rights." King knew Mikey had been in prison, so should have said, "You're on parole" (not probation). Although a layperson might use probation and parole interchangeably, an employee in the criminal justice system (such as a detective) should know the differences between the terms and use the right one. A parolee is given an early, conditional release from prison and has fewer "rights" than a probationer. (00:47:10)
Character mistake: David Dastmalchian is the Polka-Dot Man, hyphenated in the comics, and in the end credits of the movie. Then again, when Waller threatens to kill everyone off, the name of the character appears in print as Polka Dot Man, no hyphen. (01:49:40)
Character mistake: Immediately after kissing (through masks) and having close contact with JJ, Valeria removed her protective mask and went to check on her sick/crying child. Valeria was clicking her tongue, kissing her child on the face/head and putting her hands around the child's ears/hair. Valeria did not take appropriate preventive measures for contracting and/or spreading COVID-19. (00:18:40 - 00:19:29)
Character mistake: The man on the phone told Mr. Lee he wanted $960,000 cash plus $1,726,000 transferred into his account. Because the Deputy Manager was killed when the bomb in his car exploded, Mr. Lee was later told he had to pay for his share, another $1,726,000 - so he needed to transfer $3,456,000. But $1,726,000 + 1,726,000 = $3,452,000. (00:11:20 - 00:20:32)
Character mistake: Whenever Catherine visits the Baroness with young Estella, before she gets murdered, she asks the Baroness for money so that her and Estella could start a new life. Since Estella is being spoken about, the Baroness is aware of her at this point. However, later on in the movie, the Baroness questions John, "What did you think I meant when I said take care of the problem?!" Implying she thought Estella had already been killed when she was a baby.
Character mistake: In the very beginning at the baseball game the runner is running to second base and the fielder doesn't even try to tag him out. Just runs right by him and gets the ball to the pitcher. (00:00:53)
Suggested correction: The center fielder missed the ball and the right fielder got it. The second baseman was at the border of the infield and outfield and the right fielder may not have noticed that the short stop moved to cover second base. By this time, the players might have been more concerned over the opposing team scoring a run because a player had advanced to third base. It was a "revealing" mistake or overall "stupidity" by the team as each player was playing "musical positions" more so than good baseball.
With regard to "revealing", the players may have been instructed to be active on the field and cover bases for each other as needed and this was the "mess" they produced.
Suggested correction: Baseball players make mental errors all the time, even major leaguers.
I've watched the scene a few times and can't agree or disagree with the mistake, but it certainly doesn't look like a mental error one would see in a game, even a little league game. It just looked like two kids were given directions what to do and the timing might have been off and the director on set didn't bother changing it. (I'm not disagreeing or agreeing with the correction either, just making a statement to help others decide).
